How this service works
Resolve a food product barcode (UPC, EAN-13, EAN-8, etc.) to structured product metadata via Open Food Facts — the CC0 community-maintained database of >3M food products. Returns product name, brand, ingredient list, allergens, nutriments (per-100g + per-serving), Nutri-Score grade (a-e), NOVA processing classification (1-4), Eco-Score, categories, manufacturing origin, packaging, and product image URLs.
Output
Returns structured product metadata including product name, brand, full ingredient list, allergens, per-100g and per-serving nutriments, Nutri-Score grade (a–e), NOVA processing classification (1–4), Eco-Score, product categories, manufacturing origin, packaging details, and product image URLs — sourced from the Open Food Facts CC0 database.
Example use cases
Example prompt

Technical details
Endpoint
GEThttps://2s.io/api/food/barcode-lookupWhen to prefer
Use this endpoint when you need to resolve a physical food product barcode (UPC, EAN-13, EAN-8, etc.) into rich structured nutritional metadata including Nutri-Score, NOVA processing level, allergens, and ingredient lists. Prefer it over general web search when you need machine-readable, structured nutrition data from a trusted community database with >3M products. Ideal for diet tracking apps, allergen checkers, grocery assistants, or any agent needing food product facts from a scan.
Side effects
- Barcode not found in Open Food Facts database — product may be too niche or not yet catalogued
- Invalid barcode format (must be 6–14 digits) — returns validation error
- Product entry exists but has incomplete community-sourced data — some fields may be null or empty
- Payment required error if x402 micropayment header is missing or invalid
- Rate limiting or upstream Open Food Facts API unavailability
